** Due to the sensitive nature of our work, candidate must be a US Citizen. 

Location: Mukilteo, WA  

Pacific Defense is designed to support the DoD’s disciplined movement to modular open standards. The company’s approach inherently enables what it refers to as a rapid prototyping paradigm – embedding a commercial mentality into the defense industry. Products are designed from the outset for modern, AI-driven autonomy and CMOSS and SOSA-aligned hardware and software solutions. This includes state-of-the-art processing that can readily follow the evolution of commercial technology with complete data sharing across networks and platforms. 

Who are we looking for? 
We are seeking a Software Engineer – Networking and Time Synchronization to design, implement, and maintain secure, high-performance network infrastructures that support our defense programs. This role involves working closely with cross-functional engineering teams to ensure the reliability, security, and scalability of classified and unclassified networks in compliance with Department of Defense (DoD) standards.  The ideal candidate possesses a strong understanding of Ethernet MAC layers, 802.11 protocols, switching concepts, and precision time protocols like PTP/NTP. 

Requirements

Key Responsibilities 

• Design, configure, and manage enterprise network infrastructure (LAN/WAN, VPN, VoIP, and secure wireless). 

• Develop and debug embedded software for networking devices, potentially including firmware development. 

• Analyze network traffic and performance to identify and resolve bottlenecks. 

• Contribute to the development of system architectures and design specifications. 

• Implement and maintain precision time protocols (PTP/NTP) for accurate time synchronization across systems. 

• Implement and maintain network security measures including firewalls, intrusion prevention systems, and encryption technologies. 

• Support and optimize network performance through proactive monitoring, troubleshooting, and root cause analysis. 

• Investigate and resolve complex software defects and performance issues. 

• Maintain compliance with DoD cybersecurity policies (e.g., RMF, STIGs, NIST 800-53). 

• Collaborate with system engineers, cybersecurity teams, and program managers to integrate networking solutions into defense systems. 

• Provide technical documentation, network diagrams, and configuration standards. 

• Support the setup and maintenance of both classified and unclassified networks. 

• Participate in network modernization projects, technology refresh initiatives, and system migrations. 

Required Qualifications 

• Bachelor’s degree in Computer Science, Information Technology, or related field (or equivalent experience). 

• Active [Secret/Top Secret/TS-SCI] clearance (or ability to obtain). 

• 3+ years of experience in network engineering, preferably in a defense or government contracting environment. 

• Proficiency in C/C++ programming. 

• Experience with Linux development environments. 

• Familiarity with network debugging tools (e.g., Wireshark, tcpdump). 

• Knowledge of network security protocols (e.g., TLS/SSL). 

• Proficiency in configuring and managing Cisco, Juniper, or similar network hardware. 

• Strong understanding of TCP/IP, routing protocols (BGP, OSPF, EIGRP), timing protocols (PTP, NTP), VLANs, and VPN technologies. 

• Experience with network monitoring tools (SolarWinds, PRTG, or equivalent). 

• Knowledge of DoD security standards and hardening guides (STIGs). 

Preferred Qualifications 

• Experience with embedded systems development. 

• CCNA, CCNP, or similar industry certifications. 

• Familiarity with DISA networks and DoD Information Network (DoDIN) operations. 

• Experience supporting mission-critical, high-security environments. 

• Understanding of RF communications or SATCOM integration in defense networks.
